Cautionary signs
Cautionary (warning) signs are a category of traffic signs specifically designed to alert drivers to potential hazards or unusual road conditions ahead, such as narrow bridges, sharp curves, or school zones.

Informative signs give general guidance, directional signs indicate routes or destinations, and regulatory signs enforce mandatory rules — none of these describe hazard-warning signs.
